Geometry, like other areas of mathematics, is most effectively and enjoyably learned by observing, touching and experimenting. Therefore, the best way for children to discover this exciting field is through manipulative geometry. There is a wealth of manipulative materials with which children can explore, deduce and learn the geometric properties of figures and bodies as well as internalise increasingly complicated geometric concepts. I believe that including them in the classroom can provide us with an impressive richness and encourage children's interest and meaningful learning. Here is an example of a geometry manipulative material that has caught my attention:                                                            Geometric blocks This material consists of a set of flat figures with six different shapes: equilateral triangles, squa...

Hello everybody! I have found a tool called "geoplano" and I think it is very interesting and useful, that's why I have decided to create this post so you can get to know it too. With this tool we can work on geometry in a manipulative and experimental way so that children understand what they are studying and doing while having fun. Some examples of topics that can be worked with this game are: Concave and convex polygons, triangles, height, perimeter, area, circles, sides, vertices, quadrilaterals etc... I attach the video below!

I think that visual aids are a very good tool to capture the attention of students and in this case I have found a video that in my opinion can be very useful as an introduction or review, this is very appropriate for dealing with geometric bodies, faces, edges, polyhedra, curved figures....  Here it is, I think it is very interesting and useful! This could be a good option to differentiate and understand the area and perimeter of figures:  

Mandalas are symbols used in Buddhism and Hinduism that are made up of a set of different shapes and concentric geometric figures. There are many benefits when applied to children, such as: improving concentration and encouraging creativity and patience, reducing stress, etc.  We can also use them to work on different transversal contents including geometry, art, religion, etc.  I think it can be a fun tool with which to work in different ways and encourage the interest and attention of students.

One topic I had to bring to the classroom during my internship at La Presentación School was enlargements and reductions. In particular, my classroom was quite disinterested in mathematics and I thought of doing it in a more manipulative way. To do this I divided the class into groups of 5 and assigned each group a colour.  After that, I gave each group a set of geometric figures of the colour they had been assigned. The task of each group was to write down the name and size of each of the shapes and then make an enlargement and a reduction of each of them. Finally, a joint mural is made by all the groups where the different shapes are stuck together with their corresponding enlargements and reductions and the process and the result is explained next to each one of them.  The final result is a poster that can be put up in the classroom as decoration to keep the process in mind.

  A good way to work on teaching is to make students see the content as useful and familiar, that is, to work in everyday situations or environments. That is why I thought that a good idea would be to use road signs to work on geometry. And why road signs? Well, there are numerous signs of different shapes, sizes, colours and meanings, so I think that bringing them into the classroom would be a very positive reinforcement. Moreover, these objects are present in the daily life of students and often go unnoticed, so talking about the meaning of these can be a good social and civic competence and help to work and learn from respect.  I attach below an image of different traffic signs that we could use to show you the great diversity that we could work with: Likewise, traffic lights, pedestrian crossings and signs painted on the ground could also work. My idea would be to analyse and work with existing signs and finally make a project in which you invent new signs in groups, takin...

A good idea to give the pupils a change of scenery is to take them on an excursion. In this case, it has occurred to me that an activity I myself did when I was little and which involved a lot of cross-curricular content and in particular, geometry was an outing to the Alhambra where we were able to contemplate numerous mosaics.  Well then, I think that an interesting idea could be to go on this excursion and, in groups, take photos of the geometric shapes they find, with special emphasis on the mosaics. After that, in the next maths session, they will take the photographs they have taken and create their own mosaics based on what they have seen. Later, the different compositions will be shared and used to decorate the classroom.

I think that this didactic proposal would be a good option to work on different areas of the subject with transversal contents such as Physical Education, Mathematics and Art Education. Specifically in the mathematical field we can find: Axial symmetry, magnitudes: area, angular amplitude and length and types of figures. 1. Visit a football pitch and calculate the area and perimeters of the markings on it.  2. After having seen what a football pitch looks like, design different playing fields using different plane figures, draw on them what the halfway line, the areas and the goals would be. If the pitch were shaped like any other polygon, would it be equally symmetrical? Investigate by folding and mark the line that would correspond to the axis of symmetry where possible.  3. Work on identifying the types of lines and polygons in the fields designed from the previous activities.  

  Tangram is a puzzle made up of 7 geometric pieces: a parallelogram (rhomboid), a square and 5 triangles. The aim of this game is to create figures using the 7 pieces and avoiding overlapping them.  That is why I think it is very appropriate to use this activity in the classroom, as well as familiarising children with different geometric shapes, it is a good tool for developing their spatial sense and visual perception.  Below I attach a video that explains and exemplifies different figures that can be carried out.

 Did you know that there are artists who make geometric art? And what is geometric art, you may ask?  Well, this is an artistic tendency that consists of combining compositions using different geometric shapes to create different types of results through them, there are abstract paintings, sculptures, realism, etc. This trend is becoming more and more common and characteristic, that is why here are some of my favorite artists related to this trend along with a significant and representative work of each one, I hope yours! - Luján Marcos -  Pilar Barrios - Geray Mena - Valentino Sibadon - Marco Moreira

Hello everyone!😉 I'm Marieta and this is my geometry blog, a space where I will share different news, curiosities and interesting facts about this subject I'm taking in 3rd year of my degree. I hope we learn and share a lot together about the subject and that it serves as a tool, it is a pleasure to start this little geometric adventure.  Hola a todos 😉  Soy Marieta y este es mi blog de geometría, un espacio donde compartiré diferentes noticias, curiosidades y datos interesantes sobre esta asignatura que estoy cursando en 3º de carrera. Espero que aprendamos y compartamos mucho juntos sobre la asignatura y que nos sirva de herramienta, es un placer empezar esta pequeña aventura geométrica.
